New icq packet format

[0xLaurenzo]

Changes the icq packet format. Also this removes auth of query types from ICQ for easy testing
The packet format changes from the old version:

// InterchainQueryPacketData is comprised of an ABCI query request and type of query.
message InterchainQueryPacketData {
  repeated tendermint.abci.RequestQuery requests = 1 [(gogoproto.nullable) = false];
}

// InterchainQueryPacketAck is comprised of an ABCI query response with non-deterministic fields left empty (e.g. Codespace, Log, Info and ...).
message InterchainQueryPacketAck {
  repeated tendermint.abci.ResponseQuery responses = 1 [(gogoproto.nullable) = false];
}

to the new version:

// InterchainQueryPacketData is comprised of raw query.
message InterchainQueryPacketData {
  bytes data = 1;
}

// InterchainQueryPacketAck is comprised of an ABCI query response with non-deterministic fields left empty (e.g. Codespace, Log, Info and ...).
message InterchainQueryPacketAck {
  bytes data = 1;
}

// CosmosQuery contains a list of tendermint ABCI query requests. It should be used when sending queries to an SDK host chain.
message CosmosQuery {
  repeated tendermint.abci.RequestQuery requests = 1 [(gogoproto.nullable) = false];
}

// CosmosResponse contains a list of tendermint ABCI query responses. It should be used when receiving responses from an SDK host chain.
message CosmosResponse {
  repeated tendermint.abci.ResponseQuery responses = 1 [(gogoproto.nullable) = false];
}
